Which of the following is TRUE?
A. Acetylcholine is the neurotransmitter released at both sympathetic and parasympathetic effector cell receptors.
B. In the sympathetic nervous pathway, sodium ion channels will be targeted by norepinephrine in the heart.
C. In the sympathetic nervous pathway, chloride ion channels will be targeted by norepinephrine in the heart.
D. In the parasympathetic nervous pathway, sodium ion channels will be targeted by norepinephrine in the small intestine.
Homework Answers
Ans A. True, Both sympathetic and parasympathetic preganglionic neurons are cholinergic, meaning they release acetylcholine (Ach) at the synapse in the ganglion.
B. True, The sympathetic nervous system (SNS) releases the hormones(norepinephrine)to accelerate the heart rate. sympathetic nervous pathway, sodium ion channels will be targeted by norepinephrine in the heart.
C. False, the sympathetic nervous pathway, not chloride ion channels will be targeted by norepinephrine in the heart.
D.True, The parasympathetic system is responsible for stimulation of "rest-and-digest" or "feed and breed"activities that occur when the body is at rest. In the parasympathetic nervous pathway, sodium ion channels will be targeted by norepinephrine in the small intestine.

11. Acetylcholine is both an excitatory and inhibitory ligand depending on the location of its receptor. What does Acetylcholine do that makes it "excitatory"? a. It causes a cell membrane to depolarize and produce Excitatory Post Synaptic Potentials b. It opens K+ ion channels when it binds to its receptors c. It causes a cell membrane to hyperpolarize 12. The bonding of Acetylcholine to its muscarinic receptors on smooth muscle causes gated K+ channels to close. This action is described...
